Rock melicgrass is an upright, clumping perennial grass, boasting narrow, arching green leaves that lend a fine-textured look. Its standout feature is the elegant, plume-like flower spikes which emerge in late spring, swaying gently above the foliage in the breeze, and offering a delicate visual appeal. Typically thriving in open woodlands, rock melicgrass adapts well to various light conditions, contributing to its resilience and charm in naturalistic landscapes.
